The uncle of the two-year-old boy shot dead in his stroller in Brooklyn last month is wanted for a robbery in which the tragic tot’s father is also a suspect, sources said.

Anthony Hennis, 22, the father whose baby was killed by a bullet meant for him, was named a suspect two days ago in a robbery of a teen in Brownsville.

Today, cops said Anthony’s brother, Ammany Hennis, 20, is also wanted in that robbery.

The robbers approached a 19-year-old man on a No. 3 train as it headed south to the Saratoga Avenue station at 1:30 p.m., Thursday, cops said.

The two men threatened the teen and his sister and demanded his watch and wallet, cops said. The teen surrendered his watch and was punched in the face by the slain tot’s father before the train arrived at the station and the duo bolted, police said.

A female passenger recognized Anthony Hennis from newspaper photos of him that appeared after he refused to talk to detectives investigating the slaying of his 16-month-old son, Antiq, while Hennis pushed his stroller in Brownsville on Sept. 1, sources said.

“You know who that was?” she asked the teen, before explaining Hennis’ notoriety.
